Multiplicative inverse is a number which when multiplied with the current number, the answer unit (that is, 1).
Now,
1.725 = 1725/1000 = 69/40
Inverting this and multiplying it with the results yields 1. That is,
69/40*40/69 = 1
Therefore, the multiplicative inverse of 1.725 is 40/69

Given data:
random sample size n = 1000
Population size is N - 2,000,000
P = 0.49
We know


Probability for having X =520
sample proportion 




Answer:
The answer is 1296
Step-by-step explanation:
Step-by-step explanation:
c) since m = undefined => the equation is
x = -2
d) the equation is
y-2= -1/7 (x+7)
=> y = -1/7 x -1+2
<=> y = -1/7 x + 1
Let h equal the length of the party in hours
200.66 + 30.53h = 322.78
now just solve for h :)
30.53h = 122.12
h = 4
so the party was 4 hours long
